X-ray photoelectron spectra of inorganic molecules. IX. Distinction between bridging and terminal metal-chlorine bonds in metal halide clusters of rhenium(III) and molybdenum(II)

Lattice and Valence Electronic Structures of Crystalline Octahedral Molybdenum Halide Clusters-Based Compounds, Cs2[Mo6X14] (X = Cl, Br, I), Studied by Density Functional Theory Calculations

“…Since these doublets originated from spin–orbit coupling, profile fitting was performed assuming the presence of two different halogen species. Indeed, the presence of two halogen ion components in XPS spectra has been reported, − with these two peaks attributed to X a and X i . The results of peak fitting are summarized in Table .…”

X-ray photoelectron spectra of inorganic molecules. 28. Sulfur 2p binding energies of molybdenum complexes believed to contain a coordinated partial disulfide bond

“…Full details of the experimental procedure are described elsewhere. 23 where 2LH and L2 represent respectively the neutral and the anionic forms of the bidentate ligands (in I-IV) and the tetradentate ligands (in V and VI) and acac = acetylacetonate. Complete synthetic details and other physical properties will appear elsewhere.…”

“…The values were calculated from the data in Table III, on the assumption d (the distance between the metal ions) = 6.9 Á3 and the bandwidths (Avw2) 4.5 X 101 23 456789(nitrophen complex,) 5.0 x 103 (phen complex), 4.7 x 103 (oimethylphen complex), and 4.7 x 103 cm™1 tetramethyiphen complex).…”

Catalytic Characteristics of a Rhodium Complex Attached to an Aromatic Polyamide

“…Catalytic deactivation was much less in the polymer-bound catalyst system shown in Figure 6. It has been postulated that the ligands surrounding the metal ions may influence the selectivity of the catalyst (Hamer and Walton, 1974;Houghton, 1973;Morrison and Burnett, 1971;Morrison, 1971;Osborn et al, 1966). The observed loss in activity cannot be attributed to loss of rhodium, for as shown in Table I1 no change in rhodium content occurs with use.…”

“…Selectivity Characteristics. It has been postulated that the ligands surrounding the metal ions may influence the selectivity of the catalyst (Hamer and Walton, 1974;Houghton, 1973; Morrison and Burnett, 1971; Morrison, 1971;Osborn et al, 1966). The ligand is in fact changed by attachment to the Nomex polymer.…”
